Nice art! Unfortunately I can't play it, as it takes a very long time to load and then either right as it loads or right before, it crashes the browser tab. Safari (Mac), Firefox, Chrome, Brave all crash. One time I was able to get into the game on Firefox and then it locked up after a minute or so of clicking. I've not seen this happen before in a browser game. Hope you can figure it out!
So it looks like unfortunately Godot 4.x currently has no MacOS support for web builds.
I did however make a MacOS build that might work. You'd have to download it, and it's possible your Gatekeeper will try to block it. See the link for help: https://docs.godotengine.org/en/stable/tutorials/export/running_on_macos.html#do..
